The l, the] said element is preferably of parallelepipedic construction of wafer thinness as indicated at 19 and preferably having a base surface 20, and generally'designated ll. v

The illustration of Fig. l is the basis of the further modifications illustrated in the various views and the tray means for the manufacture of the said artificial icicle element.

The element illustrated in Fig. 1 may be produced in a tray25illustratedinFigures5and6,andconsistsofa tray portion 26, having a reinforced rib 27.

' The said tray is preferably molded of a plastic material, although other materials which will permit the tray to be flexed reciprocally and torsionally about its geometric cen ter, would also be satisfactory.

The tray is provided with two handle elements, one at each end, designated 28, and having a cross bar or sec-' tional reinforcement 29 "to provide strength and rigidity inviewofthestrainorstretstowhichthetraymaybe subjected.

The tray portion 26 is subdivided longitudinally by a median web portion 30, which is raised at its central portion, and tapers downwardly toward the end of the tray as indicated at 32.

It is subdivided by webs 31, which are raised to the same level as the web 30, so as to permit similar ice trays 25, to be placed in a superimposed position within a freezer unit, without the trays adhering to one another; that is, to prevent adherence of the trays, one with its adjacent tray on which it may be superimposed.

1 In that connection it is to be noted that any liquid with which the tray may be filled would level off with the ribbed edge 27 thereof, so that the level of the congealed 'nwhichcasethe thehkes,orcrystals31wrthm Thetraymayalsobeusedinconnectionwiththeacm thebeveledportionflof thecentralwebfldhusgiving andnnpartinggreaterngidrty totwistthetrayaboutitsgeometriccenterorlocusQSas ihdicatedlFiglO.

The core means 22, formed within the bored openings 45 of the tray, tend to unite the frangible elements 11, making the structure sligh y more rigid and increasing its brittleness, thereby intensifying the breaking, chipping, and flaking effects resulting when this tray is subjected to ti: reciprocal, torsional as indicated in Fig. l

A sliditly modified form of tray means is indicated in Figures 16 and 17. The core means 22 being replaced by substantially rectangular cross-sectional web formation in the icicle 23 and designated 24, resulting by slotting the WebsZBmdSIasseeninFig. 17.

A slight taper is inherent in the slotted portion 48 of the tray, so that the tray, when manufactured, may be readily removed from the mold. The tray illustrated in Figures 14 and 15 would require slightly more expense to produce the bores 45 within the webs 33 and 31. at the same time maintaining the outer end walls of the tray free of openings.

In actual use, any of the trays illustrated, may be filled with water to the level of the beaded portion 27, then placed in superimposition in the compartment of a deep freeze unit, the same being allowed to freeze so that the liquid will congeal. The trays are then ready for use and may be subjected to torsional movements to produce the flakes, chips, and ice crystals.

The artificial icicles designated 21 may also be produced in the tray illustrated and subjected to the same torsional fiexure reciprocally in order to produce flakes,

The element 18 may be sold and separately manufactured as indicated in Fig. 1, without the tray means. They [they] may be placed in a bag such as 47 and subjected to blows by a light mallet or by striking the same against a hard surface in order to produce flakes, chips, and ice crystals. The same procedure may be adopted for the icicles generally illustrated and designated 23 or 21.

The trays illustrated may also be used in connection with the cover plate 43, which will retain the crystals, and not permit the same to be dissipated from the tray,
